A tarn is a small mountain lake or pond that forms in a glacial basin, typically created by the erosion of rock and soil by a glacier. As the glacier moves, it carves out a depression in the landscape, which can then fill with water as the glacier melts. If the basin is not drained, it can hold water, resulting in a tarn. These bodies of water are often found in high-altitude areas, surrounded by steep rock walls.
